Soundguard record preservative?

Anyone here ever use this? Any Idea what it was made of?
The advertisements for this stuff used to kill me how the untreated record was just lathing away as being played. Can't believe the better business bureau let the ads fly.

Soundguard is a dry lubricant. It was orginally created as a lubricant for the Apollo space program. The lunar rover and other mechanical devices needed a dry lubricant that would not evaporate in a vacuum, and which would not be so sticky as to cause lunar dust to gum up the works. Obviously, this had somewhat limited commercial use, and the developer sought other uses.

I've used it on quite a few records. It did not seem to attact or hold dust other otherwise leave a sticky residue after it had been buffed off the record. The surface of the record did feel smoother after application (as should be the case with a lubricant) and static charge buildup was also reduced. I haven't noticed any long term problems with the product (records that were treated sound good to this day), but, then again, I haven't really tried to make any kind of rigorous comparisons.

Sound Guard is a great product. Before CDs I had and still have over 300 vinyl records. I would treated brand new with the 'Preservative'. The first play always accumulated residue on the stylus, from then on the records were clean and static free. Beware of imitators, Sound Guard is made by the Ball Corp in Muncie IN.
